Dynamic Load

With the load cells inserted as shown in 
the figure, push a Cart with its extra 
mass across the bridge. Zero the load 
cells before the measurement. Examine 
which members are under tension or 
compression.

Note that the Load Cell Amplifier can 
support up to six Load Cells in any 
combination (5 N, 100 N, or both).

Calibration.

See the instructions that came with the load cells for details about 
how to connect the load cells to an interface or datalogger. Follow 
the instructions to calibrate the load cells and use them to collect 
data. (Load cells are factory calibrated; however, you can re-cali-
brate them in software or on the datalogger. See the documentation 
for your software or datalogger for instructions.)

Large Structures Construction

The manual illustrates construction of twenty large structures such 
as trusses, bridges, and cranes. The descriptions show what com-
ponents are used for each structure and how they are connected to 
each other. Close-up photographs show the details of construction 
where possible.
